Code P1112 Description
When a vehicle's onboard computer system detects the P1112 code, it signifies an issue with the Intake Air Temperature (IAT) sensor, specifically an intermittent fault. The IAT sensor is responsible for measuring the temperature of the air entering the engine, allowing the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. An intermittent fault suggests that the sensor is providing inconsistent or unreliable readings to the ECM, which can lead to various performance issues.
Common Causes of P1112
- Faulty IAT sensor
- Damaged wiring or connectors
- Corrosion or buildup on sensor contacts
- ECM issues
- Extreme temperature changes affecting sensor readings
Symptoms of P1112
- Check Engine Light illuminated
- Decreased fuel efficiency
- Rough idling or stalling
- Engine performance issues
- Failed emissions test
How to Fix P1112
- Begin by locating the IAT sensor in the intake air duct or near the air filter housing.
- Inspect the sensor and its wiring for any visible damage, corrosion, or buildup.
- Test the sensor using a multimeter to check for proper resistance readings.
- If the sensor is faulty, replace it with a new one following manufacturer guidelines.
- Clear the diagnostic trouble codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P1112
The typical repair costs for addressing a P1112 code related to the Intake Air Temperature Sensor Intermittent can vary depending on the vehicle make and model, as well as the location of the repair. In general, the cost of a new IAT sensor can range from $50 to $150, while labor costs may add an additional $50 to $150. Overall, the total repair cost could range from $100 to $300. It's important to note that specific diagnosis time and labor rates at auto repair shops can vary, so it's advisable to check with local shops for a more accurate estimate.
